Pear Ester: Ethyl (E,Z)-2,4-decadienoate

The ester's uses in flavors include fruity red, fruity yellow, fruity tropical and other fruity applications. In fragrances, it uses encompass fruity compounds for alcoholic and cosmetic perfumes.

Syntheses and Odor Characteristic of Beta-Terpinyl Esters

Our method of snythesis of terpin-1,8 diesters and eliminating one mole of acid made it possible for the first time to produce beta-terpinyl esters with interesting odour properties. This represents a major expansion of the variety of perfumery synthetics produced from turpentine.

Odor Properties of 1-(p-Alkyl)Phenylethanols and Their Esters

All the substances have, principally, similar odor characters, possessing fruity, flowery, woody, penetrant odor notes with minor rotten, moldy notes. Other characteristic notes were observed in some compounds. Odor thresholds show mostly medium values, suitable for application in perfumery products.

Flavor Bites: Hexanoic Acid

Hexanoic acid is found widely in nature and contributes to a smorgasbord of different flavors, containing some of the cheesy profile of butyric acid, but also some of the goaty allure of octanoic acid.

Flavor Bites: Octanoic Acid

Characterized by a cheesy aroma, this ingredient pairs seamlessly with a variety of non-dairy flavors.

Flavor Bites: iso-Butyric Acid

Exhibiting a complex character, iso-butyric acid is effective in a wide range of fruit and non-fruit flavors, particularly those outside of the dairy category.

Flavor Bites: 2-Phenylacetic Acid

Fruit, nut, savory, alcoholic and other flavor uses.

Flavor Bites: Lauric Acid

Though largely used in dairy flavor applications, lauric acid with its mild long-lasting taste effect and mild odor can also be used in a range of savory, fruit and fermented flavors.

Flavor Bites: 2-Methyl Butyric Acid

Use in berry, fruit, brown, fermented and savory flavors

Flavor Bites: cis-3-Hexenoic Acid

Application in berry, fruit and other flavors.

Flavor Bites: 5-Hydroxy 2-decenoic acid delta lactone

Otherwise known as massoi lactone—the key flavor component of massoi bark oil—5-hydroxy 2-decenoic acid delta lactone is known for adding a creamy note in more than just dairy flavors.

A Neurobehavioral Analysis of I-Amino Acids as Taste Stimuli

We have described several aspects of amino acid gustatory stimulation in this report. Most convey the same message: despite some peculiarities in response time courses, amino acids bear striking similarities to the salts, acids and sugars which the majority of investigators use as taste stimuli. By determining the gustatory properties of amino acids, future research into nutrition and food selection may proceed in a logical fashion through several levels of nutrient complexity and at successive levels of the nervous system.

Butyric Acid in Dairy, Fruit, Savory, Brown and Other Flavors

Despite this pungent profile, butyric acid is capable of working in a very wide range of flavors.

iso-Valeric acid makes a subtle, but very useful, contribution to hazelnut flavors at 100 ppm.

iso-Valeric Acid in Dairy, Brown, Nut, Savory, Alcoholic Drink & Fruit Flavors

The profile of iso-valeric is very much stereotypical of the primary cheese odor, without any hint of the faint goaty character that starts to creep into the series of aliphatic acids from six carbon atoms upwards.

In beer flavors, the ideal levels are a little surprising. Light, lager-style, beers can benefit from around 300 ppm, but dark beers work best with lower levels, around 100 ppm.

Decanoic Acid in Dairy, Savory, Fermented, Fruit and Other Flavors

Decanoic acid is pretty much an essential component of dairy flavors, but it can also enhance many other categories.

Pyrazine Generation from the Maillard Reaction of Mixed Amino Acids in Model Systems

In the present study, we used Kuo et al.’s previously reported selective purge-and-trap methods to study the effect of four amino acids, acting singly or in combination, on the generation of pyrazines.
